To aZZ whom it may concern.-

Be itknown that we, IVILLIAM B. MAIN and JOHN G. BURNAUGH, citizens ofthe United States, residing at Abingdon, in the county of Knox and Statecertain ncwand usefulImprovementsin Road Carts; and we do hereby declarethat the following is a full, clear, and exact description of theinvention, which will enable others skilled in the art to which itappertains to make and use the same. I p

This invention relates to road-carts, an d has special relation to theseat-springs therefor.

The obj ect of the invention is to provide a simple and improved springof the above class, designed, in addition to its spring action, toserveas the pivotal connection be tween the thills and seat-bars.

A further object of the invention is to provide springs of thischaracter which are adapted to be readily and quickly applied duringtheconstruction of the cart, and which will possess advantages in pointof inexpensiveness, durability, and general efficiency.

In the drawings, Figure l is a perspective view of a road-cart providedwith our Ill]- proved spring. Fig. 2 is a top or plan view of the same.Fig. 3 is a detail sectional view taken longitudinally through thespring and through the adjacent portion of the seat-bar. Fig. at is adetail perspective View of the spring detached.

Corresponding parts in the figures are denoted by the same letters ofreference.

Referring to the drawings, A designates the cart, which may be in themain of the usual or ordinary construction, and comprises the axle B,thills C O, cross-bar D,'seat-bars E E, and seat F.

G G designate our improved springs, which are approximately V-shaped andconsist of .any desired number of leaves.

The springs are preferably formed of steel, and are disposed one at eachside the vehicle and designed to connect the seat with the thills andrender the former yielding. The upper arms II H 01' the springs arestraight, and when in of Illinois, have invented normal position are onthe same inclined plane of the seat-bars E, to the under side of whichthey are sccu red, preferably by bolts 71..

I I designate the lower arms of the springs, which are integral with thearms H, and are provided at their rear ends with arched portions 1' '2',forming recesses which extend over and engage the cross-bar D. The upperand lower arms converge toward their front ends, and at their points ofintersection are formed transverse eyes J J. Just in front of the latterboth the upper and lower arms are preferably secured to the seat-bars byclips L L. The springs are located at the inner side of the adjacentthill, and are pivotally secured thereto by bolts M M, passing throughthe eyes J and into castings jj, secured upon the under side of thethills.

The operation and advantages of our invention will be readily understoodby those skilled in the artto which it appertains. A spring constructedas above can be readily applied to a vehicle of the character mentioned,anddispenses with any other construc tion of pivotal connection betweenthe 'thills and seat-bars other than that formed by the springsthemselves. 7

lVe claim as our invention- The combination of the thills, cross-barconnecting the same and the straight seatbars, and approximatelyV-shaped springs formed at their apexes with bearing-eyes, through whichthey are pivoted to the thills, the top arms of said springs beingbolted to the seat-bars, While the lower arms project rearwardly andover the cross-bar, said latter arms being provided with recesses orindenturcs to accommodate the latter, all arranged and adapted tooperate substantially as and for the purpose set forth.

In testimony whereof we affix our signatures in presence of twowitnesses.
